Thanks to everyone for all the help! I found the file. It is in the OS3.9 BB#1. The CD has serial.device 43.1, BB#1 has 43.4, and BB#2 has 43.7 which has been found to be buggy. I was able to leech the file I needed from the BB. The easiest way in the future will be to save it during the initial installation. I have been led to believe that 43.4 is the best serial.device. If someone else has a different opinion I would like to hear it.
